2 Claims. (Cl. 229- 14) This invention appertains to a carton for shipping curved Windshields and like glass of the socalled panoramic or wrap-around type, and more particularly to the novel formation of the inner side flap of the carton to form a cushioning and blocking member for engaging the body portion of the glass to prevent breakage thereof during transit, the invention being divided from my pending application Serial Number 515,394 filed June 14, 1955, now Patent No. 2,812,855.

One of the primary objects of my present invention is the provision of novel means for forming the inner side flap of the carton so that the same can be readily folded into the carton for forming an eflicient cushioning and blocking member for engaging the body portion of the glass and its encircling cushioning strip, with the cushioning and blocking member lying between the folded corner cushioning blocks utilized for supporting the curved wings of the glass, whereby the entireedge area of the glass will be effectively supported and blocked, so that the glass will be held against breakage and shifting in the carton.

Another salient object of my invention is the provision of a shipping carton for curved Windshields and like glass in which the inner side flaps thereof are slotted transversely across their entire widthsand adjacent to their opposite ends, defining main body portions, which are scored longitudinally, so that the main body portions of said side flaps can be folded and bent to form inwardly projecting cushioning and blocking members, the slots providing means for receiving parts of the comer cushioning blocks to effectively hold the same in their desired positions.

With these and other objects in view, the invention consists in the novel construction, arrangement and formation of parts, as will be hereinafter more specifically described and claimed, and illustrated in the accompanying drawing, in which drawing,

Figure 1 is a perspective view of my improved carton in its folded, set up position with parts thereof broken away and in section to illustrate the novel cushioning and blocking member formed on the inner side flap;

Figure 2 is a view similar to Figure l, but showing the carton ready to receive the windshield, but prior to the sealing of the carton, and

Figure 3 is a fragmentary longitudinal sectional view through the carton in its folded condition, the section being taken on the line 3-3'0f Figure 1, looking in the direction of the arrows.

Referring to the drawing in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter C generally indicates my improved carton and the same is broadly of the type shown in my mentioned pending application. Hence, the carton C includes opposite side walls 5 and 6 and end walls 7 and 8. The upper and lower edges of the side walls 5 and 6 have formed thereon inner and outer side closure flaps 9 and 10. The upper and lower edges of the end walls 7 and 8 have formed thereon upper and lower end flaps Hand 12.

2,847,152 ies a ev -1 12 s These flaps 11- and 12am formed in the same manner,- as shown in my' cfo-pending application, andhence these flap s are bent' intermediate their ends on score lines 13tofor'1n inwardly projecting V-shaped cushioning corner blocks 14'. The ends' of the V-shaped cushioning blocks 14 are provided with bent back tongues 15 and these tongues will be later referred to.

The inner side flaps 9, in accordance with my present invention, are slotted transversely, as at 16, across their entire widths adjacent to, but spaced from their opposite ends. This defines a large main central body portion 17 on these inner flaps, and the main body portions 17 are scored longitudinally, as at 18, along spaced parallel lines. Considering, for a moment, that the carton C is in its set up position, as shown in Figure 2, and the glass with its encircling cushioning strip (not shown) is placed within the carton, then the end flaps are folded inwardly along the lines 13 to form the V-shaped cushioning blocks, after which the inner side flaps 9 are folded inwardly over the glass and the tongues 15 are placed in the slots 16 and bent back over the end portions of the flaps 9, as is clearly shown in Figures 1 and 3. Both the bottom and top side flaps 9 can be creased on the score lines 18, if such should be preferred, or found necessary, but in the present instance the top inner side flap 9 is the only side flap which is folded on the score lines, for the reason that the curved windshields at their top portions curve downwardly and inwardly, somewhat. Hence, the body portion 17 of the top inner flap 9 is now folded on its score lines 18 to provide an inwardly projecting longitudinally extending tube-like cushioning and supporting block 20, and this is best shown in Figures 1 and 3.

Attention is directed to the fact that the tubular shaped cushioning block 20 lies between the corner V-shaped cushioning blocks 14 and hence both the wings and the body portion of the glass are effectively supported and blocked.

Great stress is laid on the tubular shaped cushioning and blocking member 20, in that by forming a tube great strength is obtained for resisting blows and at the same time the tubular block 20 will give somewhat to form the desired resilient support.

Changes in details may be made without departing from the spirit or the scope of this invention, but what I claim as new is:

l. A carton comprising spaced parallel side walls, end walls and top and bottom walls, at least one of said top and bottom walls including inner and outer side closure flaps, inwardly projecting V-shaped end cushioning blocks formed on the end walls and said end cushioning blocks having bent back tongues, said inner side flap having transversely extending slots disposed across the entire width of said inner flap and adjacent to its opposite ends defining a central main body portion, said body portion being weakened along longitudinally extending spaced parallel lines, the tongues of the corner cushioning flaps being insertable in said slots and over the end portions of said inner flap, the main body portion of the inner fiap being folded on the weakening lines to define an inwardly projecting longitudinally extending cushioning and blocking tube, said tube lying between the corner cushioning blocks.

2. A carton comprising spaced parallel side walls, end walls and top and bottom walls, at least one of said top and bottom walls including inner and outer overlapping side closure flaps, inwardly projecting V-shaped end cushioning blocks formed on the end walls and disposed within the container transversely thereof for engaging the ends of an article being packed in the carton, said inner closure flap being slotted transversely ad,

jacent to but'spaced from its opposite ends defining a main centrzil body portion, said 'body portion being scored longitudinally along spaced parallel lines between said 'slots and said body portion being folded .on said lines ile'fining an inwaxdly projecting tubular cushioning and filoliing member arranged between the V-.shap.ed 'end cus liionlin'giblneks for engaging-an intermediate por- 'tion of article-packed :in .the .carton.
